Obsessive

Fully updated for this second edition, Dr. Fred Penzel discusses the entire spectrum of these disorders, from the classic form characterized by intrusive, repetitive, and often unpleasant thoughts, to body dysmorphic disorder ("imagined ugliness"), trichotillomania (compulsive hair pulling), compulsive skin picking, and nail biting. He takes the reader through each step of the most effective behavioral therapies, detailing how progress is made and how to avoid relapse.
